- Abstract
Presents the results of a study to examine epigeous ectomycorrhizal mushroom richness and productivity after partial cutting in a western hemlock (Tsuga heterophylla (Raf.) Sarg.)--western redcedar (Thuja plicata Donn ex D. Don in Lamb.) forest of northwestern British Columbia. Collection of mushrooms throughout the fruiting season (July to October) for 3 years, starting 5 years after partial cutting, from plots with mesic soil conditions and residual basal areas ranging from 23 to 69 m2/ha for western hemlock and 0 to 26 m2/ha for western redcedar. Effect of partial cutting on mushroom phenology over the 3 years. Results of significant block interactions, which demonstrated that reductions in basal area of western hemlock could lead to positive, neutral, and negative responses in mushroom richness, biomass, and number of fruiting bodies; Relation of these responses were related to stand structure and the potential differences in tree vigour after partial cutting; Weak evidence that western redcedar, a host for vesicular?arbuscular mycorrhiza, had a negative effect on average taxon richness; Conclusion that the study demonstrated that partial-cutting systems could allow some timber removal without necessarily reducing ectomycorrhizal mushroom communities.
